I UNITED STATES IMPROVEMENT lN RAI Srncrnrdncrron. I, CHARLES F. PIKE,of the city and county of Providence, in the State of lthode Island,

' haveinvented certain new and useful Improvements in Apparatus forHeating (Jars; and it consists in passing the exhaust steam from S thelocomotiveengine through suitable pipes first through the feed-water inthe tender and then successively to heaters under the cars, from whencethe heat is distributed to pipes and registers in the cars,all ofwhichwill be more fully described in the following specification,referencebein g had to the accompanying drawingiorming a part thereof.

To enable othersskilledin the art to make and use my invention, I willnow proceed to more definitely describe the same.

, In the drawing, Figure 1 is aplan of a train -1 connected, showing myapparatus in position. Fig. 2 is a side viewof the same. Figs. 3, 4, 5,6, and 7 are enlargedviews of the locomoti've, tender, and car, with myapparatus in position. i

In the drawing, A represents a locomotive; B, the tender; and B, a car.The exhaustpipes O Q of the locomotive are connected to 3 the smokearch,and are arranged under the footboards onleach'side of the locomotive. Atthe rear end of the locomotive they turn down a short distance and thenpass into the tender B, running along the bottom thereof,

and heat the feed-waterfin the tanks. The eX-- haust steam then passesthrough suitable pipes at a to the heaters E,arranged under each car,

into the air. .In summer the exhaust steam may be blown out through apipe, I), by closingthe cock c." The heaters areinclosed in anon-conducting case, cl, and contain a number of small tubes, 0, throughwhich the exhaust steam passes, heating the oil or other non-comgealable fluid in the heater E, or the tubes may be filled with oil andthe steam pass around them. Each car is provided with a double floor,ff,and between these floors are arrange the pipes F F. From the heaters 21.

branchpipe, z, leads the heat into the pipes F' F, which are'connectedby a cross-piece, g.

i The heated liquid, passing up one side and returning, pass'esthroughthe pipes h into the bottom of the lieaterE, to be there again heated,and so on automatically, keeping up heater a trap-do a constantpirculation. To gain access to the and finally, at the. end of thetrain, is blown PATENT CHARLES F. PIKE, or rnov'rnnuon, RHODE ISLAND.

floor of the car, or a door in. the side of the case 01. The heatdeveloped by the pipes F F passes through registers G, shown in dottedlines, which are arranged between the seats of the cars and ventilatorsH in the sides of the cars, with an opening at the bottom to create aconstant current of air, and thereby keep the cars well ventilated; itbeing well known -that the cold air by its gravity descends, and theheated air will follow after, until the cars are well warmed and anequal temperature obtained throughout. In the bottom of the heaters arearranged small cooks for letting out the condensed water. The pipes areall connected by flexible, universal, or slip joints of the usual kind.

The great advantages of my invention are,

first, perfect safety, there being but one fire on a train-viz., in thefurnace of the 1000lI10-' tive'and of course no accidents can occur fromupsetting of stoves, and thereby the liability of being burnt to deathisavoided. An equal temperature can be maintained in the whole car, andnot, as now with stoves, the passentherefrom and those in the centernone; second, saving-of fuel in the stoves.

When it is desired to heat the'cars before starting the virgin steam maybe run through the pipes and heaters until the train is in motion, whenthe exhaust steam may be used, which heretofore was consumed forcreating a draughtin the loeomotive itself to assist in the combustionof the fuel.

Having thus described my invention, what 1 claim, and desire to secureby Letters Pat ent, is-- 1. The arrangement of exhaust -pipes O, pipesto F k i, heaters E, registers G, and ventilators H, all substantiallyas shown, and for the purpose set forth.

2. The method herein described for warming and ventilating railroadcars, consisting in passing steam (waste or virgin) through pipes incontact with a system of code or pipes inclosed in air-fines, boxes, orchambers or pipes, andthe liquid by automatic circulation heats the air,so as towarm'andventilate the cars, substantially as set forth.
